Reasons to Choose PPR Pipes


PPR pipes and fittings are currently the most widely used plastic pipes in cold and hot water systems. Their main advantage is that they do not corrode, are resistant to many chemicals and have a long service life. They have a very good price-quality ratio and are easy to install.


One of the key components of any PP-RCT system is the fittings. Fittings are used to connect two or more pieces of pipe together, and they come in a variety of shapes and sizes to accommodate different types of connections.


There are three main types of fittings that are used in PP-RCT systems:butt fusion fittings, electrofusion fittings, compression fittings.Known for high quality products and competitive prices, we are one of the leading FITTINGS PRODUCT Pumps Manufacturers and Suppliers. Please feel free to buy FITTINGS PRODUCT sold in our factory.

There are three main types of pipe fittings: butt fusion fittings, electrofusion fittings, and compression fittings. Butt fusion (BF) fittings are generally defined as a welded device used for joining two pieces of thermoplastic material. Electrofusion (EF) fittings are saddles or couplings that have an electrically conductive inner surface. They are used to join two pieces of pipe together by heating the inner surfaces and then cooling to form a permanent bond. Compression (CF) fittings are generally defined as a non-permanent connection between two pieces of pipe that uses mechanical force to create a watertight seal.


1.Application of FITTINGS IN PP-R


VALTEC Polypropylene and brass combined (polypropylene with threaded brass inserts) fittings which are meant for polypropylene pipe circuits used for heating, cold and hot water supplies and technological installations.

2.Features of FITTINGS IN PP-R

▪ With material of polypropylene Random Copolymer (type 3) ▪ Brass material - CW617N or as required.
▪ The additional EPDM gaskets improves the reliability of the sealing ▪ Healthy and safety, conforming to drinking water standards
▪ Resistant to high temperatures, good impact strength ▪ Convenient and reliable jnstallation, low construction expenses
▪ Excellent heat-insulation property from minimum thermal conductivity ▪ Lightweight, convenient to transport and handle, good for labor-saving

▪ Light colors and excellent design ensure suitability for both exposed and hidden installation ▪ Recyclable, environment-friendly, accords with GBM standards


3.What are the Advantages of PPR Pipes?


If you want a pipe that is corrosion-resistant, lightweight, and flexible but still has high durability, PPR could be the material you are looking for. Let us have a brief look at some of the major advantages of PPR pipes.


Corrosion resistance: PPR pipes have a low corrosion rate in water environments or when exposed to weathering agents such as atmospheric oxygen and carbon dioxide. Compared with a steel pipe which corrodes roughly at 10-6~10-5mm/year in normal conditions, the corrosion rates of PPR pipes are between 10-11~10-9mm/year. The anticorrosive performance of products is good enough to make them last longer than metal materials under the same environmental condition.

Lightweight: The density of most plastic materials is usually lower than that of water, but the density of PPR is even less than half that of water. This not only makes transportation conditions better but also reduces the workload during laying and lifting operations.

Flexibility: Compared with metal pipes (such as iron/steel or copper), plastic pipe has good flexibility; it can be wrapped around corners without sharp angles or bends, which makes it easier to install.

High durability: Plastic pipe made of PPR material used for underground piping systems can last longer than steel mainlines in an under-ground environment due to its corrosion resistance, lightweight and flexibility features. Unlike common perception, plastic pipes do not easily break when bent too sharply at a small angle within 180 degrees.


3.Technical Specifications

▪ Working pressure - 25 bar;

▪ Maximum operating temperature of 95 ° C;

▪ Range of the pipe diameter 20-125 mm.




In conclusion, PPR piping is an excellent alternative to the more expensive PVC and copper piping options. They have been used in developing countries' pipeline infrastructure for decades. They have become increasingly popular in recent years due to the affordability and availability of materials required for their manufacture, as well as their greater efficiency when installed correctly. If buried in the ground, it can last up to 50 years and is more energy efficient than other pipes that don't hold their shape or corrode easily.
